The best and most reliable servers can be got from
hostsailor.com and
asvhost.com.
They were incredibly friendly and knowledgeable and basically told me everything I needed to get started (it was my first site). Since then the uptime and reliability has been great and the control panel was not bad either! I had an issue with bandwidth recently and the support was great at working out a deal for me. I would recommend them without hesitation!
